A Historic Properties Inventory for the Sky Harbor Airport Comprehensive Asset Management Plan, Sky Harbor International Airport, Phoenix, Maricopa County, Arizona

The City of Phoenix (COP) Aviation Department has prepared a Comprehensive Asset Management Plan (CAMP) Short Range Development Plan for the Sky Harbor International Airport (Sky Harbor) in Phoenix, Arizona, to guide development at the airport over the next 20 years (herein referred to as the Sky Harbor CAMP Project). The plan proposes improvements to the airfield and the construction of two new Crossfield Taxiways, expansion of the passenger terminal, a grade change of the Union Pacific Railroad within the study area, development of a North Cargo Area, and redevelopment of the South Area. Implementation of the Sky Harbor CAMP Project requires the approval of the Federal Aviation Administration (FAA) and the Federal Railroad Administration. The FAA must approve the changes to the airport layout and the use of federal funds; the Federal Railroad Administration must approve the use of federal funds. Because federal decisions are needed, the project is subject to compliance with the National Environmental Policy Act (NEPA) and National Historic Preservation Act (NHPA). The COP Aviation Department is currently preparing an environmental assessment to disclose the potential impacts of the plan for compliance with NEPA. SWCA Environmental Consultants (SWCA) was tasked with identifying historic properties within the APE to assist the FAA and the COP to comply with NEPA and NHPA review responsibilities. Historic property identification for the Sky Harbor CAMP Project was conducted in several stages, including background research, archaeological reconnaissance, and an architectural survey of the built environment. Because the planning period for the Sky Harbor CAMP Project extends to 2030, properties constructed up to 1980 would reach historic age by that time. Therefore, evaluating properties constructed up to 1980 (i.e., pre-1981) considers the 10-year lifespan of the Sky Harbor CAMP Project as a whole.
